RAZOR-STFIOPPING DEVICE.

SPECIFICATION forming part of Letters Patent No. 772,286, dated October 11, 1904. Application filed AprillQ. 1904. Serial No. 203,856. (No model.)

To aZZ whom it may concern:

at (Jork, Ireland, have invented certain new and useful Improvements in Razor-Stropping Devices, of which the-following is aspecification, such as will enable those skilled in the art to which it appertains to make and usethe same.

The object of this invention is to provide an improved raZor-stropping device by means of which a razor may be conveniently stropped or sharpened whenever necessary and which is also effective in operation and simple in construction; and with these and other objects in view the invention consistsin a razor-stroping device constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a side View of my improved razor-stropping device looking in the direction of the arrow on of Fig. 2; Fig. 2, a front view thereof; Fig. 3, a section on the line 3 3 of Fig. 2, and Fig. I a section on the line 4 4 of Fig. 2.

In the practice of my invention I provide a frame comprising a horizontal top member a and two depending side members a and a and passing horizontally through the side members (6 and a and in the top portion thereof is a main shaft 6, to the opposite ends of which are secured arms which project forwardly and backwardly and are curved upwardly and in which are mounted rollers 6 The arms 6 in the form of construction shown at each side of the machine are formed integrally, and connected with the central portion of one of said arms at the left-hand side of the machine in the form of construction shown is a segmental gear 0, the teeth of which are directed downwardly, and in the form of construction shown the shaft 6 also projects through said segmental gear, and the arms Z2 at each end of the shaft 6, are rigidly secured to said shaft.

The frame of the machine, or the side members a and (0 thereof, are provided below the shaft 6 with laterally-directed members (0 which support parallel supplemental shafts (Z,

on the outer ends of which are mounted depending supplemental arms 0Z the lower ends of which extend downwardly and are curved inwardly, and these arms are provided at their lower ends and at the front and back of the device with parallel shafts. d and laterally thereof with parallel shafts d. The side a of the frame in the form of construction shown is also provided below the members a with a short gear-shaft c, which passes therethrough and to the outer end of which is secured a segmental gear 6 which meshes with the segmental gear 0, and connected with the inner end of the shaft 0 by a universal joint 0 is an auxiliary shaft f, one end of which is mounted in the lower end of the side a of the frame, as shown at f in Fig. 2, and the side a of the frame is longer than the side a and the shaft f is thus supported in a downwardly-inclined position, said position ranging downwardly from the side a of the frame and transversely of said frame. Inclosing the shaft f and ranging concentrically thereof is a tubular spring-casing g, which is connected with said shaft by screws and said screws are provided between the shaft and the casing g with collars one of which is shown in full lines in Fig. 4: and both of which are shown in dotted lines in Fig. 2, and these collars .hold the tubular spring-casing in proper relative position with reference to the shaft f, and said casing g is slotted or open longitudinally of the bottom thereof, as shown at g.

Arranged within the tubular spring-casing g are longitudinal spring-jaws it, between which the shaft f passes, and these jaws are provided with depending members H, which pass through the slot or opening in the bottom of the casing g and are adapted to grasp and hold the back of a razor-blade d, as shown in Fig. 3, and the jaws h are pro vided with handle members if, which pass upwardly through slots in the casing g and which are separated by web 9 which forms apart of said casing g. i

I also provide a razor strop or strap j, which passes over the rollers 6 which are supported by the arms 6 and the separate ends of which are then passed downwardly on the inner sides of the shafts (Z and be tween the shafts (Z and (F in the lower ends of the arms (F, as clearly shown in Fig. 3, and by pulling downwardly on the end if of the strop or strap j the arms 6 will be thrown into the position shown in full lines in Fig. 3, and by pulling downwardly on the end f of said strop the said arms will be thrown into the position shown in dotted lines in Fig. 3, and at the same time the shaft f'and the parts g, ]L2, and b will be thrown into the corresponding positions shown in full and dotted lines in Fig. 3.

The frame of the device is also provided with a suspending hook or similar device it, which is secured to the top plate a of said frame, and in practice when it is desired to sharpen a razor the handles 72, of the jaws h are forced together, and the razor-blade is placed between the jaw members 7L2, as clearly shown in Fig. 3, where it is held by the spring action of the tubular casing g.

It will be understood that my improved razor-stropping device may be suspended from any suitable support, and when the razorblade is in position a pull on the end 1' of the strop or strap 1' will force said razor-blade into the position shown in full lines in Fig. 3, and the said end of the strop or strap will be pulled downwardly over one side of the edge thereof, as will be readily understood, and a pull on the end 1' of the strop or strap will throw the blade into the position shown in dotted lines in Fig. 3, and the said end of the strop or strap will pass downwardly over the opposite side of the edge of the blade, as will be readily understood, and the supporting of the blade in a downwardly-inclined position facilitates the operation of the strop or strap in sharpening the edge thereof, as will be readily understood.

The shafts (Z may be made to serve as rollers, if desired, as may also the shafts (Z and d", and while I have described the parts 6 as rollers simple shafts may be used in this position, if desired; but it will be seen that the shafts (Z and (i in the lower ends of the supplemental arms (Z operate only as guides for the strop or strap 1' and to control to an eX- tent the movement of the various parts of the device.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In adevice of the class described, a frame having parallel side portions, arms mounted on said side portions and adapted to swing in a vertical plane and the ends of which are curved upwardly and connected by parallel shafts, .parallel supplemental shafts mounted in the opposite sides of the frame and below said arms, a gear-shaft mounted in one side of the frame below the supplemental shafts and geared in connection with one of said arms, an auxiliary shaft connected with the inner end of the gear-shaft and ranging transversely of the frame, means connected with the auxiliary shaft for holding a razor, supplemental arms connected with the opposite endsof the supplemental shaft and curved downwardly and inwardly, and parallel guideshafts mounted in the lower ends of the supplemental arms at both sides of the device, substantially as shown and described.
